Analysis of three main causes of excessive wear of automobile tires
I often encounter many car owners asking why their tires always wear faster than others. Why do other cars of the same brand and model not have to change tires for two or three years, and they only opened it for a year, and the specialty store Request a tire change?
1. The tire pressure is abnormal for a long time.
Tire pressure is the life of the tire. If the pressure is too low, the deformation of the carcass will increase, and cracks will easily occur on the side of the tire. At the same time, excessive heat will be generated, which will cause the rubber to age, fatigue the cord, and break the cord. If the air pressure is too low, it will also increase the tire ground contact area to accelerate the wear of the shoulders; if the air pressure is too high, the tire cord will be subjected to excessive stretching and deformation, and the carcass elasticity will be reduced, which will increase the load on the car during driving. Shock will produce internal cracks and bursts. At the same time, too high air pressure will also accelerate crown wear and reduce rolling resistance.
2. Front wheel positioning is not allowed.
The front wheel positioning has a great impact on the service life of the tire, especially the front wheel toe and front wheel camber are the main factors. Front wheel camber mainly accelerates the wear of the shoulders, that is, partial wear; front wheel toe mainly accelerates the wear on the inside and outside of the tire.
3. Bad driving habits.
In addition to handling the situation while driving, the driver should choose to drive on the road, avoid sharp stones, glass, metal, etc., which may puncture and scratch the tire, avoid chemical sticking to the tire, and avoid corrosion of the tire; On arched roads, try to center as much as possible to avoid and reduce the center of gravity of the car, reduce the increase in tire load on one side and cause uneven tire wear. Reasonable loading is basic common sense. In general, overload is 20%. Tire life is reduced by 30% and overloaded by 40%. Tire life is reduced by 50%. In addition, sharp turns, emergency braking, high-speed starting, and rapid acceleration will all have an impact on tire damage and should be avoided by drivers during driving.
